Been in your boat. Stuttered since I was 10. Am now 26. While it won't go away it should get alot better. I went from not being able to have any form of conversation to now barely having any issues. My advise is to either look into speech therapy or even better some cities have a stuttering group. Being able to talk about your experience with others who understand the situation is sometimes the best thing. You've got this. It's all uphill from here.
